I got my 50Art and it works really well on the 5D3 but not so much for the 60D. Focus is off and it seems consistent. The camera store doesn't have any in stock and may not be able to get me another copy before my exchange/return time is up.

So as another alternative I could buy their USB dock and preset a focus preference on the lens..

And my question is:

Does the software allow me to set the lens differently for different camera bodies? Leave everything as-is for the 5D3 and change it to whatever it needs to be when it's mounted on the 60D?

Looks like Sigma will have to deal with AF reports first and check this before release of the 85mm f/1.4 Art. This is not good advertisement for Sigma and their products.My 50mm f/1.4 Art does not have AF problems. I am extremely happy with my copy.

Did you order yours on Day 1?

I pre-ordered mine about half a month ago and B&H sent me an email a few days ago basically saying "We don't have anything to ship to you but we haven't forgotten that we've charged you.."

I know Sigma is a 2nd tier brand... but if the lens is really that good, they would be giving it away at $800. Especially when their main competition is the Otus which is $4000. Is Ford really going charge $10,000 for a mid-size sedan because Honda is selling their's at $20,000?

Not to mention, the 50 art would come in at a lower price than the 35 art?

Makes sense but how great would it be if it's really 790... I'll order one the day it comes out..

I'm really looking forward to this. Sigma art lens have a really good reputation. If this is a sharp as the hype Sigma is getting my money. The Canon 1.4 was so fragile (better build quality my ass) I had two of them go bad (broken auto focus) so I just stuck with the the old series 1 1.8. Hoping for good things and a reasonable price but I will settle for super sharp

I'm on my 2nd 50/1.4.. first one's auto focus broke twice, the second one's shutter diaphragm is about to be stuck whenever stopped down (less than 2 years old) so I'm using it at 1.4 only and need a 1.8 for smaller aperture....
